How to send logs using SYSLOG and TLS from a windows service?

Question

I am creating a Windows Service that will be sending logs to a remote server using SYSLOG. This server requires the logs to be sendt using TLS.

I am currently using Microsoft.Extensions.Logging.Log4Net.AspNetCore(Log4Net) to achieve this. But it seems log4net's RemoteSyslogAppender does not support TLS(RFC5425).

<?xml version="1.0" encoding="utf-8"?>
<log4net debug="true" threshold="ALL">
  <!-- Doc: http://logging.apache.org/log4net/release/sdk/index.html -->
  <!-- From Xml-Schemas, add Common\ConfigAndInfo\log4net.xsd -->
  <appender name="SYSLOG" type="log4net.Appender.RemoteSyslogAppender">
    <remoteAddress value="%env{SYSLOG_URL}" />
    <remotePort value="514" />
    <appName>Application</appName>
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%message%newline"/>
    </layout>
  </appender>

  <root>
    <level value="ALL" />
    <appender-ref ref="SYSLOG" />
  </root>

</log4net>

I've seen a Nuget package(https://www.nuget.org/packages/syslog4net/) that adds TLS support, but it hasn't been updated since 2017. So I am a bit hesitant to use that.

Anyone found a solution to this? Seems like log4net is the goto library for logging in .NET? Strange that it doesn't support something as common as TLS?

Serilog with the Syslog sink did the trick!
